(b) 57 Co (tumor detection)
(c) 51 Cr (red blood cell mass)
(d) 67 Ga (tumor detection)
Assuming the solution has a heat capacity of 4.18 J/°C·g and assuming no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in units of kJ/mol.
A certain type of sugar dissolves in water, but the solution created does not conduct electricity. Therefore, the sugar does not form ions when dissolved in solution.
A star is estimated to have a mass of 1 1036 kg. Assuming it to be a sphere of average radius 7.0 105 km, calculate the average density of the star in units of grams per cubic centimeter.
A solution was prepared by mixing 70ml of 4.00 mol/L HCl and 30.0 mL of 8.00 mol/L HNO3. Water was then added until the final volume was 500ml. What is the [H+] and what is the pH ?
Write the equation for the reduction reaction. D) If the potential of the silver, silver ion electrode, E standard sub Ag+, Ag is taken to be 0.000V in oxidation or reduction, what is the value of the potential for the oxidation reaction, E standa..
A 4.70 g nugget of pure gold absorbed 285 J of heat. The initial temperature was 24.0°C. What was the final temperature.
Calculate the pH of the titration mixture after 10.0, 20.0 and 30.0 mL of base have been added. (the ka for acetic acid is 1.76 x 10^-5).
Chlorine consists of two major isotopes with the following atomic masses: 35Cl (34.9689 amu) and 37Cl (36.9659 amu). The average atomic mass of chlorine is 35.4527 amu.
A solution is prepared by mixing 79.0 mL of 5.00 M HCl and 34.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+ ], [OH - ], and the pH for this solution.
A cylinder of oxygen gas contains 26.4 g of O2. Another cylinder, twice the volume of the cylinder containing oxygen (and at the same conditions of pressure and temperature), contains CO2 gas.
A balloon is filled to a volume of 9.00 multiplied by 102 mL at a temperature of 18.0°C. The balloon is then cooled at constant pressure to a temperature of 1.00 multiplied by 102 K. What is the final volume of the balloon?
A quantity of ice at 0°C is added to 66.4 g of water in a glass at 55°C. After the ice melted, the temperature of the water in the glass was 15°C. How much ice was added? The heat of fusion of water is 6.01 kJ/mol and the specific heat is 4.18 J/(..
